Alligator’s inflate-thru valve caps are a time, money and labor saving solution that can reduce your tire pressure check time by up to 65%.

As an industry leader and expert in flow-thru cap technology, Alligator outperforms all other flow-thru caps on the market.  You can inflate, deflate and gauge directly thru the valve cap saving time during inflation and pressure checks. The caps seal like a high pressure cap, yet offer the convenience of an inflate-thru extension.

V2B and DS-P vs. Other Inflate-Thru Valve Caps

There are many lower cost, lower quality inflate-thru valve caps on the market today. At first glance they may resemble the V2B and DS-P “Gator Caps”; however, for durability, performance, and resistance to contamination and corrosion, there is no substitute for the genuine German design and quality of the V2B and DS-P.

The Myers V2B and DS-P Seal is located away from the opening Contamination does not have a direct path to the seal Contamination is directed away from the airflow
Other inflate-thru valve caps Seal is located near the mouth of the cap Contaminants have a short and direct path to the seal Contaminants are sucked into the valve core, restricting airflow and causing leaks that lead to early failure
A Look Inside of the V2B and DS-P Caps Heavy-duty housing Precision-fit brass components Incorporates two built-in heat resistant seals, preventing air pressure loss even if the valve core is damaged or dirty The end face is completely sealed to repel dirt and water Genuine German design and quality
